I know aftermarket exhausts is swappable from 96-00

I bolted on my stock 99 Si exhaust onto my 99 EX and it was longer so that tail pipe stuck out...

i need to yank off my apexi n1 off it to put on my EM1 so i'm looking to buy a stock 98 EX exhaust setup for $30 to put on

i took a look at the aprt numbers on http://www.majestichonda.com and they are different from 98-99...

any help???
